To all whom it may concern:-

and EDWARD, R. Rnnvns, citizens of the United States, residing at Oohimbuain the county of hlranklin and State of Ohio, have invented a certain new and useful Improvement- Balanced ProportioningJ alves for Explosive-Engines, of which .the following is a s ecification; I i

t is well known that to obtain the greatest efiiciency in explosive engines the explosive agent should contain its components, gas and an, in proper proportions. Because gas varies in qualityespecially natural gas as compared with artificial-it is important that the engine-be provided with means capable of nice and wide adjustment exactly adapting it for the use of the gas at hand. Such means have heretofore been roposed but they have been bulky, difiicult Qi adaptation to required conditions, and troublesome to keep clean.

f The object-of the present invention is to remedy these defects and toprovidea (301111 pact and simplified constructlon adapted'to all the ordinary varieties of gas and in which the size and cost of the device are reduced, and in which the parts are not so subject to the accumulation of oils, tar and dust called gum-and to have the efliciency of their operation affected thereby,' and in which tie apparatus is nicely and prom tly adjustable for the use of'any given qua 'ty or kind of gas, and after adjustment, is automatically maintainedj The invention consists in. the construction hereinafter described and claimed, the inven tron not being confined in its practical embodiment to precisely the forms of the parts shown.

and forming at its outer side with the casing 1 an air chamber 16.

3 is formed with ports 3 and 3 chamber communicates through a port 3 with the manifold 4 that leads to the cylinder or cylinders of the engine. Withih the easing 1 is a tubular valve device? generally of cylindrical form and provided at its lower end withgas ports 2 and at its upper end with gas ports 2*, and annular ribs 2 constituting the valves operating as hereinafter described. The tubular valve device 2 is vertically movable in ports 3' and 3 of the u per and lower portions of the-wall 3, said in conjunction The and the valve being adapted to close said ports and to cooperate therewith to vary the capacity of the passage from the air chamber 16 to the .The longitudinal ribs 2 serve to aid in guiding the tubular valve device in its movements, but these ribs can be dispensed with.

Enclrcling the lower end of the tubular valve is a rotatable bushing or sleeve 5 provided with ports 5. This bushing is secured in place by a rin 5 bolted to the main casing and is furnis ed with a suitable; handle 6 secured thereto 6 by means of which handle the ports 5" in the bushing or sleeve can be turned into and out of coincidence with the orts 2 in the lower end of the tubular va ve, see Fig. 7.

The character 7 designates'a stem con nected with the lower end of the tubular valve, said stem projectin downward through a suitable opening in t' e lower end of the sleeve to the exteritir of" the casing.

with a set screw being provided Fig. 3 is a horizontal section on the line yy 5 Fig. 2; Fig. 4 is an end view looking-at the right hand side of the valve-chamber'as seen in Fig. 1; hig is a plan view of the lower end oi'the valve clmmber. Fig. ,6 is a detail in side view 51nd section of, the valve and portof a pin 9 on a square block, siown in broken lines, sliding in'a slot W on said lever. One end of said lever is connected by a. suitable connection with the lower end of the valve stem 7, while the other end of the lever is connected by a suitable connection with the upper end of a sliding rod 10. The sliding rod 10 is connected to an ordinary centrifugal governor device, as seen at ,11, so that when said goverhor device is operated by the operation of the engine the tubular valve device is, drawn down to bring the valves thereon to th. desired given posiand Fig. 7 is a llorizontalsection onjthe line 2-2 Fig.6. ff"

in the several views ldesignates. the main or outer inclosing shell or casingj This ens-1 ing has a gas inlet 1 and an air inlet l ip Formed ithin. the chamberl is a wall 3- tion with reference to the ports 3" and 3 to 1 also forming, in conjunction with the main the mixing chamber, thereby aflordmg the l shell, an air chamber, said Wall contalmng av proper openings for the passage of air to the mixing chamber 15. By adjusting the ini- 5 crum bracket 8 to the right or to the left on the projection 1 the length of the two arms of the lever on each side of the l'ulcrum pin 9 is varied, consequently varying the position. ot the valves on the tubular valve device with reference to the ports 3 and 3* when the governor device is in operation, and the area of the air passage to the mixing chamher is correspondingly varied. By shifting the handle 6 ol the sleeve or bushing the r 5 area of the opening formed l j the cooperating gas ports 2" and 5 is increased, and reversely by shifting said handle to the left the area of such passage is diminished (or entirely closed.) it; will thus be observed that a very exact proportioning of the area of both the air and gas passages can be had. The outer casing can be provided with a scale indicating the position of the handle 6 for a given quality of gas.

12 designates a spring arranged on the stem 7 at the exterior of the -asing and press- ,ing on an adjustable nut 52'' to lend to draw the tubular valve down.
